i think he means if he did a compression test what should his reading be, i used to know the formula to figure it out but i forgot

I fixed the prob I had and also took apart the three layer gasket I had and only used 1 layer

w/ this gasket set up and a 11:1 piston it read 170psi on the compression meter
Thanks for the replys
